Small objects are delivered to the 2 - m inclined chute by a conveyor belt A which moves at a speed V1 = 0.3 m / s . If the conveyor belt B has a speed V2 = 0.9 m / s . and the objects are delivered to this belt with no slipping , the coefficient of friction Ik between the objects and the chute is 0.5 , calculate the incline angle ( Ⓡ ) of the chute .

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

For the closed feedwater heater below, feedwater enters state 3 at a pressure of 2000 psia and temperature of 420 °f at a rate of ix10 ibhr. the feedwat extracted steam enters state 1 at a pressure of 1000 psia and enthalpy of 1500 btu/lbm. the extracted er leaves at an enthalpy of 528.7 btu/lbm steam leaves as a saturated liquid. (16) a) determine the mass flow rate of the extraction steam used to heat the feedwater (10) b) determine the terminal temperature difference of the closed feedwater heater
